PORTLAND, Ore.—John C. Fuller, former owner and president of Fuller Brothers Inc. in Clackamas, Ore., died April 10 in Portland. He was 76.
Mr. Fuller invented and held patents for a number of processes for automatic tire bead venting for retreading and manufacturing bia-ply tires. His first invention was Seal-Zit, a rust inhibitor for truck tire rims, which is now called Tire Life.
About 10 years ago, Mr. Fuller retired from the company and sold it to his sons. He remained active as an inventor, and his last product was a tire protectant called Sunblock that is now sold nationwide.
Mr. Fuller is survived by his wife, Arlene, and five children, including his son, Tim, who is the current president of Fuller Brothers.
